Abstract
The utility model discloses a cavity-through multi-line connector for the underground coal mine, which solves the technical problem that because the terminals between anti-explosion cavities are more and more, the wiring cavity becomes big. The utility model comprises an anti-explosion cavity (6), and an anti-explosion hole (7) fixed on the anti-explosion cavity (6), wherein an annular steel jacket (2) is arranged in the anti-explosion hole (7), the annular steel jacket (2) is fastened in the anti-explosion hole (7) through the annular brim of the annular steel jacket (2) by a fastening bolt (8) to be meet the requirement of the anti-explosion combination surface, the inner end of the annular steel jacket (2) is provided with a first round molding plate (1), the outer end of the annular steel jacket (2) is provided with a second round molding plate (3), a wire passing hole is provided with copper core polyvinyl chloride insulated wires (4), a polyester insulating material (5) is arranged between the first round molding plate (1) and the second round molding plate (2). The utility model is suitable for the electrical connection between the anti-explosion cavities in underground coal mine.
Description
Technical field
The utility model relates to wears the multi-thread connector of cavate on a kind of explosion-proof cavity that is used under the coal mine.
Background technology
At present, the circuit that is used for communication contact under the coal mine between the flame proof cavity is by on explosion-proof main chamber connection chamber being set, and finishes being electrically connected between an explosion-proof main chamber and another the explosion-proof main chamber in that binding post is set on the connection chamber again.Along with the raising of down-hole automatization level, make binding post more and more, directly cause the wiring cavity to become big, thereby increase the cost of flame proof cavity, brought difficulty also for the explosion-proof processing of flame proof cavity.
Summary of the invention
The utility model provides a kind of be used under the coal mine wear that the multi-thread connector of cavate solved that prior art exists because the binding post between the explosion-proof cavity is more and more, directly cause the wiring cavity to become big, thereby increase the cost of flame proof cavity, brought the technical problem of difficulty to the explosion-proof processing of flame proof cavity.
The utility model overcomes the above problems by following scheme:
A kind of being used for worn the multi-thread connector of cavate under the coal mine, comprise the flame proof cavity, the explosionproof hole that on the flame proof cavity, fixedly installs, one end has the annular steel bushing of the annular the brim of a hat that stretches out, described annular steel bushing is arranged in the explosionproof hole, the annular the brim of a hat of fastening bolt by annular steel bushing is fastened on annular steel bushing in the explosionproof hole and satisfies the requirement of flame proof faying face, place, the inner at annular steel bushing is provided with the first circular molded plate, place, outer end at annular steel bushing is provided with the second circular molded plate, on the first circular molded plate and the second circular molded plate, be provided with a plurality of electric wires and pass through the hole, electric wire passes and is provided with copper core BLV in the hole, is provided with polyester insulated material between the first circular molded plate and the second circular molded plate.
The described first circular molded plate and annular steel bushing are matched in clearance, and the described second circular molded plate and annular steel bushing are interference fit.
The utility model adopts multi-thread casting technique, and it is little to take volume, and the service efficiency height is safe and reliable, the electrical connection under the suitable coals mine between the explosion-proof chamber.
